At 25 MHz, the CPUXV2 runs polyphase energy calculations across seven ADC channels with headroom for communication stacks. The 512 KB Flash can hold a full metering firmware stack including the TI metrology library, calibration constants, and several months of interval data logging. The 16 KB RAM is sufficient for real-time variables and a modest buffer, but not for large graphic frame buffers or extensive protocol parsing — keep the communication payloads lean or use external serial RAM via SPI. The Flash is field-reprogrammable, supporting in-system firmware updates over UART or I²C.","metaTitle":"Texas Instruments MSP430F67781IPEU 16-bit MCU, 25MHz, 512KB Flash, 128-LQFP","metaDescription":"MSP430F67781IPEU 16-bit MCU with MSP430 CPUXV2, 25MHz, 512KB Flash, 16KB RAM, 7x24-bit sigma-delta ADC.
